    PR: Samsung Introduces World’s Largest Capacity (15.36TB) SSD for Enterprise Storage Systems

    March 03, 2016

    Samsung Electronics, the world leader in advanced memory technology, announced that it is now shipping the industry’s largest solid state drive (SSD) – the “PM1633a,” a 15.36 terabyte (TB) drive.

    First revealed at the 2015 Flash Memory Summit in August, the 15.36TB SSD is based on a 12Gb/s Serial Attached SCSI (SAS) interface, for use in enterprise storage systems. Because the PM1633a comes in a 2.5-inch form factor, enterprise storage managers can fit twice as many of the drives in a standard 19-inch, 2U rack, compared to an equivalent 3.5-inch storage drive.

    “To satisfy an increasing market need for ultra-high-capacity SAS SSDs from leading enterprise storage system manufacturers, we are directing our best efforts toward meeting our customers’ SSD requests,” said Jung-bae Lee, Senior Vice President, Memory Product Planning and Application Engineering Team, Samsung Electronics. “We will continue to lead the industry with next-generation SSDs, using our advanced 3D V-NAND memory technology, in order to accelerate the growth of the premium memory market while delivering greater performance and efficiency to our customers.”

    The unprecedented 15.36TB of data storage on a single SSD is enabled by combining 512 of Samsung’s 256Gb V-NAND memory chips. The 256Gb dies are stacked in 16 layers to form a single 512GB package, with a total of 32 NAND flash packages in the 15.36TB drive. Utilizing Samsung’s 3rd generation, 256-gigabit (Gb) V-NAND technology which stacks cell-arrays in 48 layers, the PM1633a line-up provides significant performance and reliability upgrades from its predecessor, the PM1633, which used Samsung’s 2nd generation, 32-layer, 128Gb V-NAND memory.

    Samsung’s new PM1633a SSD provides the opportunity for significant improvements in the efficiency of IT system investments through its high storage capacity and exceptional performance. These performance gains stem from Samsung’s latest vertical NAND (V-NAND) flash technology, as well as the company’s proprietary controller and firmware technology.

    The PM1633a SSD sports random read and write speeds of up to 200,000 and 32,000 IOPS respectively, and delivers sequential read and write speeds of up to 1,200MB/s. The random read IOPS performance is approximately 1,000 times that of SAS-type hard disks, while the sequential read and write speeds are over twice those of a typical SATA SSD. Inside the new SSD lie Samsung’s advanced controller units that support the 12Gb/s SAS interface, along with a total of 16GB of DRAM. Samsung also uses specially designed firmware that can access large amounts of high-density NAND flash concurrently.

    The 15.36TB PM1633a drive supports 1 DWPD (drive writes per day), which means 15.36TB of data can be written every day on this single drive without failure, a level of reliability that will improve cost of ownership for enterprise storage systems. This drive can write from two to ten times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies.

    Further, the drive boasts a highly dependable metadata protection mechanism in addition to featuring a data protection and restoration software tool in case of a momentary blackout, which make enterprise systems more stable and manageable.

    Starting with the 15.36TB density, Samsung will provide a wide range of capacity options in its PM1633a SSD line-up – 7.68TB, 3.84TB, 1.92TB, 960-gigabyte (GB) and 480GB later this year. With more choices in storage capacity, Samsung is reinforcing the competitiveness in its SAS SSD line-up. The Samsung PM1633a SSD line-up is expected to rapidly become the overwhelming favorite over hard disks for enterprise storage systems.

    Samsung revealed it was working on the drive last August

    Along with the 15.36TB model, Samsung will offer the PM1633a SSD in 7.68TB, 3.84TB, 1.92TB, 960GB and 480GB versions later this year.

    Samsung Electronics announced Wednesday that it is now shipping the industry's highest-capacity solid-state drive (SSD), the 15.36TB PM1633a.

    Samsung revealed it was working on the drive last August, saying it would use the same form factor as for a laptop computer: 2.5-in.

    The 2.5-in SSD is based on a 12Gbps Serial Attached SCSI (SAS) interface for use in enterprise storage systems. The PM1633a has blazing fast performance, with random read and write speeds of up to 200,000 and 32,000 I/Os per second (IOPS), respectively. It delivers sequential read and write speeds of up to 1200MBps, the company said. A typical SATA SSD can peak at about 550MBps.

    Because the PM1633a comes in a 2.5-in. form factor, IT managers can fit twice as many of the drives in a standard 19-in. 2U (3.5-in.) rack, compared to an equivalent 3.5-in. storage drive. The SSD also sets a new bar for sustainability, Samsung said. The 15.36TB PM1633a drive supports one full drive write per day, which means 15.36TB of data can be written every day on a single drive without failure.

    The SSD can write from two to 10 times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies.

    Samsung said it is betting on the PM1633a SSD line-up to "rapidly become" the overwhelming favorite over hard disks for enterprise storage systems.

    "To satisfy an increasing market need for ultra-high-capacity SAS SSDs from leading enterprise storage system manufacturers, we are directing our best efforts toward meeting our customers' SSD requests," Jung-bae Lee, senior vice president of Samsung Electronic's Application Engineering Team, said in a statement. The performance of the PM1633a SSD is based on four factors: the 3D NAND (vertical NAND or V-NAND) chips; 16GB of DRAM; Samsung's proprietary controller chip; and the 12Gbps SAS interface.

    The random read IOPS performance is about 1,000 times that of SAS-type hard disk drives and the sequential read and write speeds are more than twice the speed of a typical SATA SSD, the company said.

    Combining 512 of Samsung's 256Gbit V-NAND memory chips enables the SSD's unprecedented 15.36TB of data storage capacity in a single drive. V-NAND, or 3D NAND, is a way of stacking NAND cells one atop another like a microscopic skyscraper. Not only does it double the density of standard planar NAND chips, from 128Gbits to 256Gbits, it also increases performance.

    Samsung originally announced the 48-layer V-NAND last August, saying it also sports 3-bits per cell or multi-level cell (MLC) NAND technology.

    In the V-NAND chip, each cell utilizes the same 3D Charge Trap Flash (CTF) structure in which the cell arrays are stacked vertically to form a 48-storied mass that is electrically connected through 1.8 billion channel holes vertically punching through the arrays by using a special etching technology. In total, each chip contains more than 85.3 billion cells. They each can store 3 bits of data, resulting in 256 billion bits of data -- in other words, 256Gb on a chip that's larger than the tip of a finger.

    The 256Gb dies are stacked in 16 layers to form a single 512GB package, with a total of 32 NAND flash packages in the 15.36TB drive. Utilizing Samsung's third-generation, 256-gigabit (Gb) V-NAND technology, which stacks cell-arrays in 48 layers, the PM1633a line-up is expected to be faster and more reliable than its predecessor, the PM1633. That model used Samsung's second-generation, 32-layer, 128Gb V-NAND memory.

    In 2014, Samsung became the first company to announce a 3D NAND flash chip with a 3-bit MLC architecture. In October 2014, the company announced it was mass producing a 32-layer V-NAND chip. Then, last August, it followed up by mass producing a 48-layer V-NAND chip.

    While Samsung may be the first to do so, it's not alone in developing 48-layer 3D NAND chips. Last year, SanDisk and Toshiba announced that they were also preparing to manufacture 256Gbit, 3-bit-per-cell (X3) 48-layer 3D NAND flash chips that offer twice the capacity of their previously densest memory.

    Intel and Micron have also announced 3D NAND products. The two companies boasted that their technology would enable gum-stick-sized SSDs with more than 3.5 terabytes (TB) of storage and standard 2.5-in. SSDs with greater than 10TB.
